### problem
After creating a k8s cluster and adding an IP address with empty start and
end ports, I’m unable to delete the cluster; I get the following error:

### versions
CloudStack version is 4.20.1
### The steps to reproduce the bug
1. Create a k8s cluster with an isolated network (IP subnet e.g.
192.168.1.0/24).
2. In the Firewall tab, remove all rules.
3. Add the following rules:
- 192.168.1.0/24, port start: 6443, port end: 6443
- 1.1.1.1/32, port start: (leave blank), port end: (leave blank)
4. Stop the k8s cluster.
5. Attempt to delete the k8s cluster → deletion fails.
Workaround that succeeds
Replace the second rule with:
> 1.1.1.1/32, port start: 1024, port end: 65534
### What to do about it?
I would like to have the ability to create rules with blank fields.
